Lady Aisha (may Allah be pleased with her) narrates: The Noble Prophet (peace and blessings be upon him) was asked about a person who sees wetness but does not remember experiencing a wet dream. The Noble Prophet (peace and blessings be upon him) said: "He should perform ghusl (ritual bath)." He was asked about a person who remembers experiencing a wet dream but does not see any wetness. The Noble Prophet (peace and blessings be upon him) said: "Ghusl is not obligatory upon him." Lady Umm Sulaym (may Allah be pleased with her) asked: "If a woman sees this, is the same ruling applicable to her?" The Noble Prophet (peace and blessings be upon him) said: "Yes! Women are the counterparts of men."
